HEAT DIVERTER Filed Aug. 16, 1929 E-DZ , HI 1 Z 4 I HI E Patented July 22, 1930 ROBERT s. BAGH'ELER, or BALTIMORE, MARYLAN HEAT nivunrnn Application filed August 16, 1923. Serial No. 386,383;

his invention relates to a heat diverter and more particularly to a flue cover and de- Hector of the type generally associated with the line collar or stack of a gas cooking range for the purpose of coverlng the top of the fine or stack and defiectlng the gases comprising the products of combustion in a downwardly and forwardly direction whereby their tendency to be deposited on the walls and neighboring objects is reduced to a minimum.

The object of this invention is to provide a heat diverter that may be easily attached to flue, and also easily demountable with respect thereto for purposes of cleaning or replacing thesame, said heat diverter being of an inverted trough shaped form and provided with spaced longitudinally positioned openings in the front of said heat diverter to facilitate the discharge of the products of combustion gently and withoutviolence and discomfort ina downwardly and forwardly direction. 1

Other objects of this inventionwill'become apparent as the description thereof proceeds, reference being now had to the accompanying drawing wherein: j i Figure 1, is a front elevational View of the heat diverter and a portion of'theqflue or stack, and V I V Figure'Q, is a sectional view of the same taken on line 22, Figure 1. The heat diverter or deflector 1, is preferably a metal casting of aninverted trough shaped form and comprises a top 2, side Walls '3, back 4., and front wall 5. The side walls I 3 are formed identical to each other and con 7 'nect the-back 4 and front wall 5, which are of two different convex curvatures merging together at their upper ends to form the curved convex top 2; As is apparent from Figure 2, the radius of curvature of the back i is lessjthan the radius of curvature of the "front wall 5.

Positioned substantiallymidway between the back 4- and front wall 5and parallel with the back 4 is a which merge with th side walls 3, that are to form with the back e inner surface of the andalso forwardly through the stood'that the same is 15 attached to said bottom thereof and two openings of substantially equal area, the partitiono, the ends of,

of concave curvature, at a substantially oval,

shaped opening 7 which is adapted to fit over a similarly conventional shaped flue collar8 of a flue or stack9. i j

Formed in the front wall 5 are two spaced longitudinally disposed slots or openings 10, extending substantially the full length of said front wall; The'upper and lowerrwalls 11 and 12, respectively, of each of the slots or openings 10 are parallelto each other and are varranged diagonally with respect to the vertical, as clearly shown in Figure 2.

As the flue gases or products of combustion are discharged through the top of the flue or stack 9, they'are defiected'downwardly due to the interiorly. curved surface of the" heat diverter 1, and aredischarged through the opening'7', which incidentally is of substantially the same areaas the opening 7, openings 10,

in the front Wall 5. Due to the provision of III the openings 10, the products of combustion are diffused gently into the air at .a high level when discharged, thereby obviating the objectional blast orforceful flow of said gases in a downwardly direction through the discharge opening 7 usually felt by a person working at a gas range. y i .YVVhile. a preferred embodiment of the invention has been disclosed, it is to be undermodifications within pended claims.

susceptible of various the scope ofthe ap- -Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A'flue cover and heat diverter embodying, an inverted trough shaped casing com- 1 prising atop of varying convex curvature, the radius of curvature ofthe rear portion thereof being less than the radius "of curvature of the front portion thereof, side walls inte- 'gral with said-top,

a partition of a height said flue cover, integralside walls adjacent the dividing said bottom into less than one-halfof openmgat the rearof said flue, cover being adapted to receive therein the flue collar of a flue, and a plurality of in. the front portion a ut) of said top and, extending through the same in a diagonally downward direction.

2. A flue attachment for gas stoves having a substantially horizontal discharge opening substantially coequal in area to the line opening, comprising a substantially sem cylindrical hood having a substantially semieylindrical peripheral wall and substantially flat end walls merging thereinto, the edge portions of the walls being in the same horizontal plane and presenting a substantially rectangular opening, a partition strip extending between the end walls and dividing the opening into two parts substantially coequal in area, and a stack, or pipe, for supporting the hood a distance above the fine outlet of a stove, said stack having one end associated with the flue outlet flange of the stove and its opposite end held in one of the last named parts between. said strip and the lower rear edge portion of the peripheral wall, the front portion of said peripheral wall a substantial distance above the bottom edge of the same being provided with an outlet opening.

3. A flue attachment for gas stoves including a hood having a substantially semi-cylindrical peripheral wal and substantially flat end walls merging thereinto, the marginal edge portions of the walls presenting a substantially rectangular opening, a strip extending between the end walls and dividing the opening into two parts, and a stack, or pipe, having one end associated with the flue opening of the gas stove and its opposite end hold in one of the last named parts between saidstrip and the lower rear edge portion of the peripheral wall, the front portion of said peripheral wall substantial distance above the bottom ed of the same being provided with a plurality of outlet openings.

ii. A flue attachment for gas stoves comprising a hood having a substantially semicylindrical peripheral wall and end walls merging thereinto, the marginal edge portions of the hood presenting a substantially rectangular opening, a partition extending between the end walls substantially midway between the front and rear marginal edge portions of the peripheral wall, and a pipe having one end adapted to beassociated with 'the flue opening of a gas stove and having its opposite end held between said partition and the lower rear edge portion of the peripheral wall, the front portion of said peripheral wall a substantial distance above the bottom edge of thesame being provided with a horizontal slit.
